Digital BW, The Print

I have recently started with BowHaus too. I am using PiezoTone
Selenium ink in a Epson 1290. 

It´s a bit frustrating too make profiles from scratch when you don´t
have any training or the right tools to do it the easy way. I don't
have a densitometer and I only have a cheap document scanner to make
density readings. The CanoScan software did funny things with the
greyscales and I had to get VueScan to get usable readings for
linearization. 

The clue as I understand it, is to manipulate the ink curves so the
corrections in the linearization process are as small as possible.
This takes a lot of trial and error, especially if the default curves
for the quad inks don´t work for you and you have to go for free edit
curves. You have unlimited control and it´s a learning curve ;-)

Yesterday I finally got usable profiles for Photo Rag and EEM. Not
perfect. These papers take ink differently and this is the first time
I experience that the print really changes (for the better) after
drying. It was not like that when I used the Epson printerdriver.

I have loaded two chambers in the color cart with Middle grey and two
chambers with Light grey to extend the time between the need to refill
the cart. The chambers/slots pair use the same ink curve, but only
half of the ink limit each.

If you have better ways of fine tuning curves than me I would be happy
to share my profiles with you - and others in need.

I have limited experience making/correcting curves and I hope more
experienced users of Bowhaus and monochrome inksets will jump in here
and share their way of thinking and workflow when making curves from
scratch. The user manuals are a bit lacking in these matters. For me
manipulating ink curves is a bit like black (ink) magic. 

If you have simple questions I will answer them the best I can from my
experience.
